15 Million Degrees: A Journey to the Centre of the Sun by Lucie Green – review

Edit The Guardian 04 May 2016
A high energy photon is absorbed by a negative hydrogen ion which bubbles nearer to the surface at about a kilometre a second to release – at last – a photon of light ... Negative hydrogen ions midwife 95% of the sun’s visible light, and for every 100m hydrogen atoms in the sun’s photosphere, there is only one negative hydrogen ion....

This man's microchip can predict your future

Edit CNN 27 Apr 2016
Make that highly unconventional ... "But maybe that makes me more intuitive," he says ... Read More ... If the sample matches that for which the chip has been primed, hydrogen ions are released (as happens when pairs of nucleotides bind during DNA sequencing) ... Should no signal be sent, no nucleotides bind together, no hydrogen ions are released and no signal is sent, meaning the individual is not suffering from, or predisposed to, that condition....

Ocean acidification caused by climate change threatens shellfish

Edit The Examiner 22 Mar 2016
“When CO2 is absorbed by seawater, a series of chemical reactions occur resulting in the increased concentration of hydrogen ions. This increase causes the seawater to become more acidic and causes carbonate ions to be relatively less abundant. Carbonate ions are an important building block of structures such as sea shells and coral skeletons....

Forget waterproof phones, this device charges your phone with water

Edit Mashable 12 Jan 2016
Once the hydrogen atoms are stripped of their electrons, they become positively charged hydrogen ions and are able to move through the fuel cell's electrolyte — a membranelike substance that limits the movement of ions in the cell. At the cathode end of the cell, oxygen from the air enters and combines with the hydrogen ions that made it through the electrolyte and electrons returning from the electrical circuit....
